Lid margin rotational procedures have been used to correct cicatricial trachomatous entropion since the 19
th
century. There are two basic types of surgeries used for lid margin rotation. The first type is based on through-and-through approach combining tarsotomy and the use of sutures on the anterior lamella. The second type of surgery was suggested by Trabut, who proposed a tarsal advancement by posterior approach. We demonstrate that using a lid crease incision combines the basic mechanisms of the anterior and posterior approaches and in addition, addresses a variety of lid problems commonly found in the aged population with cicatricial entropion. After tarsal plate exposure, a tarsotomy through conjunctiva is performed as described by Trabut. Then, instead of using external sutures secured by bolsters, internal absorbable sutures can be used to simultaneously advance the distal tarsal fragment and exert strong tension on the marginal orbicularis muscle. Sixty lids of 40 patients underwent surgery with a lid crease incision. The follow-up ranged from 1 to 12 months (mean 3.0 months ± 2.71). Forty percent of the patients (24 lids) had more than 3 months of follow-up. Adequate margin rotation was achieved in all lids but one that showed a medial eyelash touching the cornea.

p. 410
David Meyer, Caroline Gooding

PMID
:26692709
To present our recent experience with intralesional bleomycin (IBI) in nonmelanoma extraocular tumors, and present previous experience on periocular capillary hemangiomas and orbital lymphangiomas in a tertiary referral hospital. This was a retrospective descriptive study of patients with eyelid and extraocular malignancies where conventional therapies failed, or surgery was contraindicated or refused and were offered IBI as an alternate therapy. All patients were recruited from the Oculoplastics Clinic at Tygerberg Academic Hospital, Cape Town, South Africa. A solution containing 1 international unit of bleomycin per milliliter saline was injected intralesionally together with 2% lignocaine in a ratio of 4:1. The injected volume was calculated to be equivalent to the estimated volume of the lesion. A multipuncture technique with a 29-gauge needle was used. Patients requiring retreatment were injected every 4–8 weeks until satisfactory clinical endpoints were achieved. Our previous experience with IBI in extensive capillary hemangiomas and orbital lymphangiomas is reviewed. Cases are presented to illustrate that IBI induced significant regression and reduction in tumor size and marked clinical improvement of the eyelid and orbital basal cell carcinomas, Kaposi sarcoma, and mycosis fungoides. The improvements obviated the need for further surgical intervention in most cases. Based on clinical experience we propose that IBI should be considered a treatment modality in select cases of the malignant eyelid and ophthalmic vascular tumors where the conventional standard of care is not possible. IBI is a reasonable alternative or adjunct to consider in such cases.

Myths in the diagnosis and management of orbital tumors
p. 415
Kaan Gündüz, Özge Yanık

PMID
:26692710
Orbital tumors constitute a group of diverse lesions with a low incidence in the population. Tumors affecting the eye and ocular adnexa may also secondarily invade the orbit. Lack of accumulation of a sufficient number of cases with a specific diagnosis at various orbital centers, the paucity of prospective randomized studies, animal model studies, tissue bank, and genetic studies led to the development of various myths regarding the diagnosis and treatment of orbital lesions in the past. These myths continue to influence the diagnosis and treatment of orbital lesions by orbital specialists. This manuscript discusses some of the more common myths through case summaries and a review of the literature. Detailed genotypic analysis and genetic classification will provide further insight into the pathogenesis of many orbital diseases in the future. This will enable targeted treatments even for diseases with the same histopathologic diagnosis. Phenotypic variability within the same disease will be addressed using targeted treatments.

Review of ocular manifestations of nevoid basal cell carcinoma syndrome: What an ophthalmologist needs to know
p. 421
Judy J Chen, Juliana Sartori, Vinay K Aakalu, Pete Setabutr
DOI

Nevoid basal cell carcinoma syndrome (NBCCS) is a rare, autosomal dominant disorder characterized by multiple basal cell carcinomas (BCCs), odontogenic keratocysts, palmar and/or plantar pits, and ectopic calcifications of the falx cerebri. Myriad ophthalmologic findings are associated with NBCCS, including periocular BCCs, hypertelorism, strabismus, myelinated nerve fibers, and disorders of the retina and retinal pigment epithelium. We performed a literature search in PubMed for articles on the ophthalmologic manifestations of Gorlin syndrome, published between 1984 and 2014. Of 33 papers, 31 were included. Although Gorlin syndrome is due to mutations in a single gene, it displays variable phenotypic expressivity. Therefore, familiarity with this disorder across clinical specialties is necessary to avoid misdiagnosis. The ophthalmologist should be included in the multidisciplinary team for the management of Gorlin syndrome in order to prevent visual loss and improve the quality of life of these patients.

PMID
:26692712
The ocular surface is a component of the anterior segment of the eye and is covered by the tear film. Together, they protect the vital external components of the eye from the environment. Injuries, surgical trauma, and autoimmune diseases can damage this system, and in severe cases, tissue engineering strategies are necessary to ensure proper wound healing and recovery. Dry eye is another major concern and a complicated disease affecting the ocular surface. More effective and innovative therapies are required for better outcomes in treating dry eye. This review focuses on the regenerative medicine of the conjunctiva, which is an essential part of the ocular surface system. Features and advances of different types of biomolecular materials, and autologous and allogeneic tissue grafts are summarized and compared. Specifically, vitrigel, a collagen membrane and novel material for use on the ocular surface, offers significant advantages over other biomaterials. This review also discusses a breakthrough microfluidic technology, "organ-on-a-chip" and its potential application in investigating new therapies for dry eye.

Determining safe surgical access to the orbit can be difficult given the complex anatomy and delicacy of the orbital structures. When considering biopsy or removal of an orbital tumor or repair of orbital fractures, careful planning is required to determine the ideal approach. Traditionally, this has at times necessitated invasive procedures with large incisions and extensive bone removal. The purpose of this review was to present newly techniques and devices in orbital surgery that have been reported over the past decade, with aims to provide better exposure and/or minimally invasive approaches and to improve morbidity and/or mortality.

Virtual surgical planning for orbital reconstruction
p. 442
Srinivas M Susarla, Katherine Duncan, Nicholas R Mahoney, Shannath L Merbs, Michael P Grant
DOI

PMID
:26692714
The advent of computer-assisted technology has revolutionized planning for complex craniofacial operations, including orbital reconstruction. Orbital reconstruction is ideally suited for virtual planning, as it allows the surgeon to assess the bony anatomy and critical neurovascular structures within the orbit, and plan osteotomies, fracture reductions, and orbital implant placement with efficiency and predictability. In this article, we review the use of virtual surgical planning for orbital decompression, posttraumatic midface reconstruction, reconstruction of a two-wall orbital defect, and reconstruction of a large orbital floor defect with a custom implant. The surgeon managing orbital pathology and posttraumatic orbital deformities can benefit immensely from utilizing virtual planning for various types of orbital pathology.

Sclerosing lesions of the orbit: A review
p. 447
Gautam Lokdarshi, Neelam Pushker, Mandeep S Bajaj

PMID
:26692715
Orbital sclerosing inflammation is a distinct group of pathologies characterized by indolent growth with minimal or no signs of inflammation. However, contrary to earlier classifications, it should not be considered a chronic stage of acute inflammation. Although rare, orbital IgG4-related disease has been associated with systemic sclerosing pseudotumor-like lesions. Possible mechanisms include autoimmune and IgG4 related defective clonal proliferation. Currently, there is no specific treatment protocol for IgG4-related disease although the response to low dose steroid provides a good response as compared to non-IgG4 sclerosing pseudotumor. Specific sclerosing inflammations (e.g. Wegener's disease, sarcoidosis, Sjogren's syndrome) and neoplasms (lymphoma, metastatic breast carcinoma) should be ruled out before considering idiopathic sclerosing inflammation as a diagnosis.

ORIGINAL ARTICLES
Upper blepharoplasty and lateral wound dehiscence
p. 452
Mohsen Bahmani Kashkouli, Mansooreh Jamshidian-Tehrani, Sahab Sharzad, Mostafa Soltan Sanjari
DOI
:10.4103/0974-9233.167813
PMID
:26692716
Purpose:
To report the frequency of lateral wound dehiscence (LWD) after upper blepharoplasty (UB), a technique and its outcome to prevent LWD.
Materials and Methods:
A retrospective review was performed for cases of LWD after UB presenting between 2003 and 2009, and then a prospective comparative study was performed between February 2009 and March 2013. For the comparison, subjects were divided into two groups based on intraoperative assessment of lateral wound tension (same technique and surgeon). Group 1 received 1-3 orbicularis/subcutaneous buried sutures (6-0 polyglactin) before interrupted 6-0 nylon skin closure. Group 2 underwent skin closure only. Subjects, who had re-operation, skin healing disorders, and incomplete follow-up (<6 months), were excluded.
P
< 0.05 was considered as statistically significant.
Results:
There were 14 (14/678, 2%) cases with LWD with a mean age of 36.2 years in the audit (2003–2009). The prospective study included 68 subjects (68/293, 23.2%) in Group 1 and 225 in Group 2. Gender and simultaneous forehead and eyebrow procedures were similar between groups (
P
= 0.3 and
P
= 0.4 respectively). Group 1 was statistically significantly younger at mean age of 41.4 years, compared to Group 2 at 56.1 years (
P
= 0.000). The frequency of LWD significantly (
P
= 0.04) decreased to 0.3% (1/293).
Conclusion:
In the presence of wound tension on skin closure (intraoperative assessment), tension relieving buried orbicularis/subcutaneous 6-0 polyglactin suturing of the lateral UB incision could prevent LWD.

DOI
:10.4103/0974-9233.167817
PMID
:26692717
Background:
We present the outcomes of bilateral myectomy and tucking of the proximal end of the muscle for the treatment of asymmetric primary inferior oblique (IO) overaction.
Methods:
This was a one.armed prospective cohort study. An ophthalmologist and orthoptist evaluated cases of primary IO muscle overaction presenting between January 2010 and December 2013. All eyes underwent bilateral myectomy and tucking of the proximal end of the IO muscle. Data were collected on ocular motility, the angle of deviation, postoperative complications, and status of hypertropia at 6. months postoperatively. The 95% confidence intervals. (CI) were calculated. The statistical significance was indicated by
P.
< 0.05.
Results:
The patient cohort was comprised of 51 patients with primary IO muscle overaction. Preoperatively, all eyes had +2 or greater overaction of the IO muscle except one patient with +1 and +3 overaction in the right and left eyes, respectively. At 6 months postoperatively, the reduction in the angle of deviation for distance and near was 32.6 prism diopters (PD) ([95% CI 30.3−34.9],
P
< 0.001) and 32.6 PD ([95% CI: 29.8−35.3],
P
< 0.001), respectively. There was no significant difference in the postoperative variation of the reduction in the angle of deviation based on gender, right or left eye, and type of horizontal strabismus. There were no cases of “A” or “V” patterns, clinically a significant IO underaction or “adherence syndrome” postoperatively.
Conclusion:
Bilateral myectomy and tucking of the proximal end of the muscle is likely an effective method of treating asymmetric primary IO muscle overaction.

DOI
:10.4103/0974-9233.167827
PMID
:26692718
Aims of the Study:
To study the frequency of meibomian gland dysfunction (MGD) in patients of diabetes mellitus with dry eye.
Materials and Methods:
A case-control cross sectional study.
Sampling:
Purposive random sampling. Totally, 200 eyes of 100 patients of diabetes mellitus and an equal number of eyes of normal subjects as control, who were gender and age matched and all of whom were symptomatic for dry eye were assessed for MGD by noting the symptoms and determining the meibomian gland expression scale for volume and viscosity, and ocular surface staining with Lissamine green, and Fluorescein sodium. All the subjects were graded for the severity of MGD. The results were compared in both the groups to ascertain whether the frequency of MGD in diabetics is significantly more as compared to nondiabetics.
Statistical Analysis:
The data were analyzed by Chi-square test for significance.
P
< 0.05 was considered as statistically significant.
Results:
There was a significant increase in the frequency of MGD in diabetics as compared to the nondiabetics.
Conclusion:
Diabetes mellitus is associated with MGD.

p. 467
Handan Akil, Fatih Celik, Fatih Ulas, Ilknur Surucu Kara
DOI
:10.4103/0974-9233.167814
PMID
:26692719
Purpose:
To assess the comorbidity of dry eye syndrome (DES) and changes in corneal curvature in children with allergies.
Materials and Methods:
This prospective, comparative, and observational interventional study included 49 patients, who presented to the Ophthalmology Clinic of a State Hospital in Turkey. There were 25 patients with clinically diagnosed seasonal allergic conjunctivitis (AC) (with complaints of itching and papilla formation of conjunctiva; AC group) and 24 healthy children (control group). There with no significant differences in age between groups. Using the ocular surface disease index (OSDI) questionnaire, we performed tear film break-up time (BUT), central reflex tear meniscus height (TMH-R) measurement, Schirmer test on both groups and evaluated keratometry (K1, K2) and spherical equivalent (SE).
Results:
Patients ranged in age from 6 to 18 years (median age, 11.79 years; 46.9% male; 53.1% female). The papillary reaction was severe in 10% of patients with AC. The prevalence of dry eye in children with AC was 12%. There was no statistically significant difference between groups for K1, K2, and SE (
P
> 0.05, all comparisons). BUT was statistically different (
P
= 0.004) between groups, indicating that a higher OSDI the tear film BUT was lower (ρ = 0.567). Statistically, significant negative moderate correlations were found between papillary reaction and the Schirmer test, BUT, and TMH.R (ρ = 0.454, −0.412, −0.419, and
P
= 0.001, 0.003, 0.002, respectively)
Conclusions:
The evaluation of pediatric patients with AC requires further attention to ensure an adequate diagnosis of DES.

Dry eye following phacoemulsification surgery and its relation to associated intraoperative risk factors
p. 472
PK Sahu, GK Das, Aman Malik, Laura Biakthangi
DOI
:10.4103/0974-9233.151871
PMID
:26692720
Purpose:
The purpose was to study dry eye following phacoemulsification surgery and analyze its relation to associated intra.operative risk factors.
Materials and Methods:
A prospective observational study was carried out on 100 eyes of 100 patients without preoperative dry eye. Schirmer's Test I, tear meniscus height, tear break-up time, and lissamine green staining of cornea and conjunctiva were performed preoperatively and at 5 days, 10 days, 1-month, and 2 months after phacoemulsification surgery, along with the assessment of subjective symptoms, using the dry eye questionnaire. The correlations between these values and the operating microscope light exposure time along with the cumulative dissipated energy (CDE) were investigated.
Results:
There was a significant deterioration of all dry eye test values following phacoemulsification surgery along with an increase in subjective symptoms. These values started improving after 1-month postoperatively, but preoperative levels were not achieved till 2 months after surgery. Correlations of dry eye test values were noted with the operating microscope light exposure time and CDE, but they were not significant.
Conclusion:
Phacoemulsification surgery is capable of inducing dry eye, and patients should be informed accordingly prior to surgery. The clinician should also be cognizant that increased CDE can induce dry eyes even in eyes that were healthy preoperatively. In addition, intraoperative exposure to the microscopic light should be minimized.

A Community-based eye care intervention in Southern Egypt: Impact on trachomatous trichiasis surgical coverage
p. 478
Ahmed Mousa, Courtright Paul, Arminee Kazanjian, Ken Bassett
DOI
:10.4103/0974-9233.167808
PMID
:26692721
Purpose:
The purpose of this study was to measure the impact of a community-based intervention on uptake of trichiasis surgery in Southern Egypt.
Methods:
Four villages where trachoma is endemic were randomly selected in the Samalout district, Egypt. Two villages were selected for intervention (intervention villages) and two matched villages for nonintervention (nonintervention villages). The intervention model provided community information sessions, door-to-door health education, screening, and improvements in the clinical capacity of eye care providers. The intervention was evaluated through two pre - and post-intervention community-based surveys that included the prevalence of trachoma and the utilization of eye care services at local hospitals. All patients with trichiasis answered a questionnaire regarding surgical utilization and barriers.
Results:
In the baseline survey, the trachomatous trichiasis (TT) surgical coverage was 22.7% (38.9% males, 16.7% females) in all villages. Following the intervention, the TT surgical coverage increased to 68% in villages that received the intervention (81.5% males, 60% females). Nonintervention villages had a TT surgical coverage of 26.1% (37.5% males, 20% females). In the intervention villages, the prevalence of TT significantly decreased from 9.4% (5.7% males, 11.8% females) to 3.8% (1.9% males, 5.1% females) (
P
= 0.013), in 2008. In nonintervention villages, there was a slight, but insignificant decrease in TT from 10.1% (3.1% males, 14.4% females) to 8.2% (3% males, 11.5% females) (
P
= 0.580). The major barriers to uptake of TT surgical services were: “Feeling no problem” (17.3%), “fear of surgery” (12.7%) and “cost” (12.7%).
Conclusion:
A community-based eye health education program with door-to-door screening significantly increased the uptake of TT surgical services. Although improvements to the delivery of surgical service are essential, they did not lead to any significant improvements in the nonintervention villages.

DOI
:10.4103/0974-9233.167821
PMID
:26692722
Purpose:
To evaluate refractive and visual outcomes of photorefractive keratectomy with mitomycin.C. (PRK.MMC) for the treatment of mild to moderate hyperopia.
Materials and Methods:
This case series enrolled 21 patients with up to +5.50 diopters (D) of hyperopia. All 42 eyes were treated with the Concerto (Wavelight) or the Technolas 217-Z (Bausch and Lomb) excimer laser. Outcome measures included best corrected distance vision acuity (BCVA) and uncorrected distance vision correction and refraction at 1, 3, 6, and 12 months postoperatively.
Results:
Mean patient age was 44.8 ± 11.3 years. Preoperatively, mean manifest refractive spherical equivalent (MRSE) was + 2.00 D ± 0.76 D and mean spherical refractive error was + 2.57 D ± 0.87 D (range, +1.25 D to + 5.50 D). At 12 months postoperatively, mean MRSE was + 0.1 D ± 0.61 D. MRSE was within ± 0.50 D of emmetropia in 29 eyes (69%), and 18 eyes (43%) had 20/20 uncorrected distant visual acuity. BCVA increased by two lines or more in three eyes (7.1%) and one line in two eyes (4.7%); 31 eyes showed no change, three eyes (7.1%) lost one line, and three other eyes (7.1%) lost two lines of BCVA. No eyes lost more than two lines of BCVA. Complications included Grade 2 peripheral haze in two eyes which cleared by 12 months postoperatively.
Conclusion:
PRK-MMC was a safe and predictable method for the correction of mild to moderate hyperopia.

PMID
:26692723
Purpose:
Oxidative stress has been implicated in the pathophysiology of glaucoma, cataract, and many degenerative diseases. The purpose of this study is to evaluate the systemic oxidative stress in black.African patients diagnosed with primary glaucoma or age.related cataract. (ARC) and compare these indices to normal control patients and between the two conditions.
Methods:
This was a descriptive cross.sectional study of consecutive recruited subjects attending a tertiary care facility. One hundred adults were enrolled and sub.grouped into: Normal controls. (
n
= 20), patients with primary glaucoma. (
n
= 40), and patients with cataract. (
n
= 40). The data were collected on patient demographics and clinical information. Ten milliliters of the venous blood was taken from each subject for the evaluation of serum biochemical indices of oxidative stress. Laboratory measurements of enzymatic and nonenzymic anti.oxidants, as well as lipid peroxidation, were conducted using established and validated spectrophotometric methods. The systemic oxidative stress was measured by the serum levels of anti.oxidant enzymes and lipid peroxidation, and compared between the groups and to a control group of patients.
Results:
Statistically, significantly reduced serum levels of glutathione, glutathione-S-transferase, superoxide dismutase, catalase, and ascorbic acid were found in the patients with glaucoma or cataract when compared with controls. (
P
< 0.05 for all). Differences in serum lipid peroxidation levels across or between the groups were nonsignificant. Serum protein levels were significantly higher among the subjects with cataract or glaucoma than in controls.
Conclusion:
Our results concur with findings in Caucasian study cohorts. This indicates that in black.Africans, primary glaucoma, and ARC are associated with increased systemic oxidative stress. This supports the existing evidence on the role of oxidative stress in these ocular disorders and reinforces the rationale for the use of anti.oxidants in the management and possible prevention of these conditions.

Purpose:
To evaluate the long.term visual outcomes and complications of the piggyback intraocular lens. (IOL) implantation compared to aphakia for infantile cataract
Patients and Methods:
In a comparative study from 1998 to 2007, piggyback IOL implantation (piggyback IOL group) was performed for 14 infants (23 eyes) with infantile cataract and 20 infants (32 eyes) who were aphakic (aphakia group) after infantile cataract surgery. Data were collected on logMAR visual acuity, and postoperative complications over a mean follow-up time of 6.2 ± 1.7 years and 5.8 ± 1.7 years.
Results:
The mean age at surgery was 7.5 ± 0.6 months and 6.0 ± 3.3 months for the piggyback and the aphakic group respectively (
P
> 0.05). At the last follow-up visit, visual acuity was 0.85 ± 0.73 (median = 0.70, interquartile range = 0.3–1.32) in the piggyback IOL group and 0.89 ± 0.56 (median = 0.86, interquartile range = 0.50–1.24) in the aphakic group (

> 0.05). There was a positive relationship between age and visual outcomes in the aphakic group (
r
= 0.4,
P
= 0.04) but not in the piggyback IOL group (
P
= 0.48). There was no significant difference between the mean myopic shift in the piggyback IOL group (–5.28 ± 1.06 D) and the aphakic group (–5.10 ± 1.02 D) (
P
> 0.05). The incidence of reoperation due to complications in piggyback IOL group was higher than aphakic group (%48 vs. %16, respectively,
P
≤ 0.01). However, in patients older than 6 months, this risk was not significantly different compared to the aphakic group.
Conclusions:
Although piggyback IOL implantation for infantile cataract is optically acceptable as a treatment option, there is no significant difference in visual outcomes compared to aphakia. The incidence in reoperation due to complications in patients aged 6 months or younger is higher than those treated with aphakia.

Cataract surgery audit at a private hospital in Saudi Arabia
p. 502
Tariq Alasbali, Nancy Maher Lofty, Saeed Al-Gehaban, Hisham S Alkuraya, Abdulrahman M Alsharif, Rajiv Khandekar
DOI
:10.4103/0974-9233.167820
PMID
:26692725
Background:
To assess the visual outcomes following cataract surgeries at a Private Eye Hospital in Riyadh, Saudi Arabia.
Methods:
This was a cohort study of cataract surgeries performed from January to June 2014. Preoperative data were collected on patient demographics presenting and best corrected distance visual acuity (BCVA) and ocular comorbidity. Data were also collected on the type of surgery, type of intraocular lens (IOLs) implanted, and complications. BCVA and refractive status at 6−8 weeks postoperatively were noted. The predictors of vision ≥6/18 were identified.
Results:
Four hundred eyes of 400 patients underwent cataract surgery. There were 235 (59%) males. Presenting preoperative vision was <6/60 in 52 (13%) eyes. There were 395 (99%) eyes that underwent IOL implantation following phacoemulsification and 4 eyes received a sulcus fixated IOL. A single piece aspheric IOL was implanted in 358 (90%) eyes and a toric IOL was implanted in 31 (8%) eyes. Postoperative BCVA was classified as a “good outcome” (≥6/18) in 320 (80%) and a “poor outcome” (<6/60) in 24 (6%) eyes. Young age (adjusted odds ratio (OR) = 0.97,
P
= 0.01), male (adjusted OR = 2.4,
P
= 0.002), and ocular co-morbidities (adjusted OR = 0.2,
P
< 0.001) were predictors of vision ≥6/18. Complications included a dropped nucleus and a posterior capsular tear in 2 eyes each. Two hundred and fifty-two (63%) eyes were emmetropic or intentionally myopic for distance. Astigmatism <2 D was present in 264 (66%) eyes and astigmatism >2 D was present in 33 (8%) eyes.
Conclusion:
The recent trend of intentional overcorrection in one eye following modern cataract surgery in order to provide some functional near vision indicates that benchmark for success in getting “good visual outcomes” postoperatively (vision of ≥6/18) may need to be revised.

Perception and attitude of a rural community regarding adult blindness in North Central Nigeria
p. 508
Victoria A Olatunji, Feyi G Adepoju, Joshua F. A Owoeye
DOI
:10.4103/0974-9233.167826
PMID
:26692726
Aim:
To determine the perception and attitudes of a rural community regarding the etiology, prevention, and treatment of blindness in adults.
Methods:
A cross-sectional, descriptive study was performed in a rural community in Kwara State, Nigeria using semi-structured questionnaire. All adults aged 40 years or older who were residents for a minimum of 6 months in the community were included. Data were collected on patient demographics, knowledge, attitude, perception, and use of the eye care facility.
Results:
A total of 290 participants were interviewed. The male-to-female ratio was 1:2. Consumption of certain types of food was an important cause of blindness as perceived by 57.9% of the respondents, followed by supernatural forces (41.7%) and aging (19%). Sixty percent of respondents thought blindness could be prevented. Age (
P
= 0.04) and level of education (
P
=0.003) significantly affected the beliefs on the prevention of blindness. Most respondents (79.3%) preferred orthodox eye care, but only 65% would accept surgical intervention if required. The level of education significantly affected the acceptance of surgery (
P
= 0.04). Reasons for refusing surgery were, fear (64%), previous poor outcomes in acquaintances (31%), belief that surgery is not required (3%), and cost (2%). About 65% used one form of traditional eye medication or the other. Over half (56.6%) believed that spectacles could cure all causes of blindness. Of those who had ocular complaints, 57.1% used orthodox care without combining with either traditional or spiritual remedies.
Conclusion:
This rural Nigerian community had some beliefs that were consistent with modern knowledge. However, the overall knowledge, attitude, and perceptions of this community need to be redirected to favor the eradication of avoidable blindness. Although an eye care facility was available, use by the community was suboptimal. Age and the level of education affected their overall perception and attitudes.

BRIEF COMMUNICATION
Prolene canalostenting in deep sclerectomy: A pilot study
p. 514
Ahmed Mostafa Abdelrahman, Yasmine Mohamed El-Sayed
DOI
:10.4103/0974-9233.167810
PMID
:26692727
Purpose:
To study the effect of implantation of a 5/0 prolene suture segment inside Schlemm's canal as an adjunct to deep sclerectomy.
Materials and Methods:
This was a prospective, interventional case series of nine eyes of six patients with open angle glaucoma. Patients underwent deep sclerectomy with insertion of a segment of 5/0 prolene into Schlemm's canal at the filtration site without suturing. The main outcome measures were: Intraocular pressure (IOP), postoperative interventions, and complications. Ultrasound biomicroscopy of the filtration area as well as the prolene suture was performed at 6 months postoperatively.
Results:
Patients were followed for a mean of 8.1 ± 4.5 months. Mean IOP decreased statistically significant from 19 ± 4.2 mmHg preoperatively to 12 mmHg at 15 months postoperatively (
P
< 0.0001). The number of glaucoma medications was reduced from 3.7 ± 0.7 preoperatively to 0 postoperatively. No postoperative complications were noted. IOP remained in the low teens in all patients out to the last postoperative visit. Yttrium-aluminum-garnet laser goniopuncture was not required in any case.
Conclusion:
Implantation of a 5/0 prolene suture in Schlemm's canal during deep sclerectomy was a safe, cost-effective adjunct to maintain the patency of the intrascleral space and Schlemm's canal thus controlling IOP for 6. months postoperatively.

Achondroplasia is an autosomal dominant congenital disorder of enchondral ossification. It is clinically characterized by low stature, craniofacial deformity, and vertebral malformation. Associated ophthalmic features include telecanthus, exotropia, angle anomalies, and cone-rod dystrophy. A 24-year-old male presented with decreased vision bilaterally and typical achondroplasia. The best corrected visual acuity was 20/70 in both eyes. Anterior segment examination was normal. Fundus examination revealed a well-demarcated circular paramacular lesion in both eyes. As macular coloboma and achondroplasia are developmental disorders, the funduscopic examination is required in patients with achondroplasia.

Tuberculous (TB) conjunctivitis was not an uncommon condition before the early 20
th
century but is currently a rare occurrence, especially in the developed countries. We report a 27-year-old Saudi female who underwent enucleation of the right eye at the age of 20 following a penetrating eye injury. She had a history of miliary TB that was treated at the age of 22. She was presented with chronic purulent discharge from her right an anophthalmic socket for 2 months. Cultures for bacteria and fungi were sterile. There was no response to empirical topical antibiotics and steroids. Direct microscopic examination of conjunctival scrapings with the Ziehl–Neelsen staining revealed no microorganisms. Histopathological examination revealed epithelioid granulomas. Polymerase chain reaction was negative for
Mycobacterium tuberculosis
DNA. TB conjunctivitis was suspected from the history of miliary TB and presence of epithelioid granulomas. The definitive diagnosis was made after prompt resolution of the ocular signs with no recurrence only after systemic anti-TB therapy.

Lipodermoid cyst: A report of a rare caruncular case
p. 528
Mohammad Taher Rajabi, Koosha Ramezani

Ocular lipodermoid cysts and solid dermoid tumors are choristomas which are described as normal tissue growth in an abnormal location. Congenital epibulbar lipodermoid comprises adipose tissue that is covered by connective tissue. They are usually located superotemporally, and basically tend not to involve the peripheral cornea. If the dermoid or lipodermoid is accompanied by other systemic conditions or ocular anomalies in young children, a consultation with an Internist or pediatrician is required to rule out Goldenhar syndrome which is a oculoauriculovertebral dysplasia. This paper reports a unilateral lipodermoid cyst which is remarkable regarding its caruncular origin, in an otherwise healthy adult female.
